# Amplify API

> Build communications workflows with the Amplify platform.

The Amplify API lets you connect your applications to Amplify communications resources. Use a consistent REST interface to work with faxes, documents, messages, calls, contacts, numbers, users, and related platform services.

All API requests use the following base URL:

```text theme={null}
https://api.amplify.xyz/v1
```
